Today on the water at Jacksonville Beach
Today at Jacksonville Beach: high tide at 12:20 AM (5.1 ft) and 12:55 PM (6.3 ft), low tide at 6:22 AM (0.3 ft) and 7:28 PM (0.5 ft). The National Weather Service forecast for today is mostly cloudy then slight chance rain showers with NE winds 10 to 18 mph, 77°F. Wind that strong can hold water in or push it out, so the real tide may run above or below these predictions. In effect now: Small Craft Advisory. Sunrise is at 7:38 AM and sunset at 6:40 PM.

Where Jacksonville Beach is
Jacksonville Beach sits at 30.2833° N, 81.3867° W on Florida's Atlantic coast, at Jacksonville Beach, FL. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1977 until 1999, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Mayport (Bar Pilot Dock) (NOAA 8720218), 8.3 mi away, and high and low water here run on average about 25 min earlier than there. The nearest weather station is Little Jetties, St. Johns River, FL, a shore station reporting wind and, at most sites, water temperature, 7.5 mi away.
The tide at Jacksonville Beach
Jacksonville Beach has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 5.6 ft, and 5.1 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.4 ft and the lower low sits 0.2 ft below the other low. For the water around it: Florida's Atlantic tides are semidiurnal, two highs and two lows a day, with ranges of 2 to 5 ft that shrink inside the lagoons.
About this station
- High tide reaches Jacksonville Beach about 0.5 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 7.6 ft on May 18, 1999.
- Lowest on record: -2.6 ft on Feb 18, 1996.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Jacksonville Beach from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.6 ft above it and mean sea level 2.5 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 3.1 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Fernandina Beach, FL gauge. Source: NOAA CO-OPS station 8720291, established 1977, gauge removed 1999. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Jacksonville Beach this month: Oct 1, Oct 25, Oct 26, Oct 27, Oct 28, Oct 29, Oct 30. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Jacksonville Beach this month: Oct 27, Oct 28, Oct 29. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for Jacksonville Beach, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
